I'm working on a character but i cant figure out which card prop in "read  itand weep" I should use. which one is it? thanks

You have to manually move it into position, and yes, it's as much fun as you think it's going to be. You can go one of two routes, move the hand to where you want it and fit cards to hand (recommended), or move cards and then fit the hand around the cards. I wouldn't try for perfection, you'll go crazy. Just make sure it looks right in the render.

Read Them And Weep Poses for Genesis 8 male has some great props and hand poses that will save you a lot of that trouble.  They are supposed to be for Genesis 8 male, but I've found they work just fine for Genesis 8 Female.
